Horsepower is just a mathematical equation.

HP=(Torque)X(RPM)/5252

This means that on ALL torque/horsepower curves that use HORSEPOWER and FT-LBS (instead of Newton Meters), the numbers will be EQUAL. its because of math. where the graph crosses has no meaning whatsoever. The numbers ARE equal at 5252 rpm (because when you plug that into the above equation, 5252/5252 = 1, so HP=Torque).

And just because the lines physically cross at 6000 or so rpm means nothing. the scaling is different. and there is NO industry standard on scaling, but there IS an industry standard on that above equation.

 

I dynoed again this weekend.

280rwhp/268tq@10 psi

For more boost I need ignition upgrade/amp, so I think 310rwhp will be quite reallistic at 13psi

261.2rwhp / 227.6 tq
is this # a bit low? any comments would be helpful. thanks!

I have video if anyone want to host it.

 

here's mine: https://www.rx7club.com/time-slips-dyno-121/my-first-dyno-wohoo-d-444016/

315/246 @ 13.5 psi getting slightly lean at the high end

250/188 @ 8 psi solid afr

one question, how does SAE correction work?

I think the torque in my graphs is uncorrected but the hp is SAE corrected, I plotted the torque graph in excell and used hp=tq*rpm/5252 formula to get the hp graph and it was lower than what the dyno graph says.

If I go the other way and plot hp but calculate tq then I get a higher torque...

 

I just saw an article at my doctors office about an FD hitting nines on street tires and 25-28 lbs a boost. I dunno know fer sure cause it was in a crazy magazine from europe.

 

Here a video of my last pull see above for results.

Mine put down 533whp this weekend. Steve Kan tuned it.

Here you go guys. This is how you make power on Pump 93 octane Fuel

20B? What type of turbo are you running?

 

Nah, both the torque and spool doesn't seem like 20B at the boost level.

Good job on the tune nonetheless!!

 

You are correct. The torque would have kicked in at a much lower level - and should be higher I would think. Damn nice numbers though.

 

this was on a 2 rotor engine with strret port low compression Scalaped rotors

 

how much power should a healthy FD fully nonsequential make with just a downpipe? 10psi

 

208.0 horsepower 180.5 torque

268.15 @ .64 bar

rest of the stuff in signature

apparently my signature isnt working

t04 housing, 60-1 wheel, p-trim

14psi

 

I pull 235 on the wheel with stock turbo, strait pipe 3 inch complete exaust, stock air intake. That been pull on a dynapack at 10 psi. It is an off you think????

 

no sounds about right...stock puts out 215-218 usually so you made an \"honest\" 20 hp with exhaust not bad. by honest i mean you didnt have to increase the boost to make the horsepower

 

I didn't touch anything on the car, just make an 3 inch exaust. The boost is 10 psi, the air fuel is 12 and the engine and everithing else is stock. This summer I will install an Emanage for increase the boost at 15 psi and that will be the last mod than I will do....the torque on the wheel is 220 pound flat curve between 3000 to 6000.
